Top tax-busting diesel company cars

  • We pick our top 10 diesel company cars under 100g/km
  • Mixture of hatchbacks, SUVs and estate cars
  • Monthly tax costs, trim and engine details included

Although we don’t like to think about it, tax  forms a key part of the decision-making process when picking your next company car.

Choose one with high CO2 emissions (if your fleet manager allows) and you’ll pay dearly in BIK. With the bands on the rise, it'll only get worse over the three or four years of ownership too. But car manufacturers are making a conscious effort to reduce CO2 emissions, and now there's more choice of low-emission company cars then ever before. 

We've highlighted 10, all of which emit under 100g/km, have five doors and use diesel engines.

 

Audi A1 Sportback


The smallest member of the Audi family is big news for the German firm, proving a huge hit. After a mid-life facelift in 2014, the engines were revised, and the 1.6-litre diesel offers a combined fuel economy of 80.7mpg and only 92g/km of CO2. That means it slots into a 16 percent BIK tax band for the current 2015/16 tax year.   

In entry-level SE trim the A1 comes with 16-inch alloy wheels, a 6.5-inch multimedia screen, DAB Radio and start/stop as standard. However, don't discount the A3 Sportback, which emits less than 99g/km of CO2 either.

Nissan Qashqai


The Qashqai saved Nissan, and was one of the most popular cars in the UK last year - and it's easy to see why. Sharp looks, low CO2 emissions, impressive fuel economy (especially from the 1.5-litre dCi Acenta+) and low running costs make it an appealling all-rounder. 

Standard equipment includes 17-inch alloy wheels, dual-zone automatic air conditioning, front and rear parking sensors, Bluetooth, automatic headlamps and wipers, DAB Radio, keyless entry, a rear view camera and a panoramic glass roof.

Volkswagen Golf

Based on the S, Bluemotion models get 15-inch alloy wheels, air-con, DAB radio, cruise control, Bluetooth connectivity and electric windows.

Skoda Fabia Estate


New for 2015 the Skoda Fabia is packed full of practical features, packs some frugal engines beneath its funky looks and has a competitive price tag to boot. Choose between the hatch and the estate, the latter of which recieves a full five stars from Parkers, and combine it with the 1.4-litre TDI engine for 83mpg and 89g/km CO2. 

We'd opt for the mid-range SE as it includes 15-inch alloy wheels, rear parking sensors, black roof rails, Bluetooth, DAB Radio and air-con. Be aware, that while the Fabia has Mirrolink, there's no on-board sat-nav - even in the options.

Ford Fiesta


Combine both retail and fleet sales together, and the Fiesta takes top UK sales spot.

Mini One D


One of the most stylish superminis available, the MINI can make sense as a company car too. The addition of a five-door model last year, plus the new 1.5-litre diesel engine bolsters its appeal - and gives it 80mpg and 92g/km CO2 emissions.

It's not easy to decide on your perfect trim - there's so many options - but the sensible choice would be the entry-level One with the Pepper Pack, with 15-inch alloy wheels, DAB Radio, daytime running lights, Bluetooth, climate control and automatic rain sensors and wipers as standard.
